How to install stainless steel corrosion-resistant pump
Due to its stable and reliable performance, good sealing performance, beautiful appearance, convenient use and maintenance, stainless steel corrosion-resistant pump is widely used in chemical, petroleum, metallurgy, light industry, synthetic fiber, environmental protection, food, medicine and other departments. Therefore, we also pay more and more attention to the daily maintenance of this kind of equipment stainless steel corrosion-resistant metal pump in this regard, and ultimately, the daily maintenance of the pump and ultimately the demolition of the installation. Below, Asia Fluid Network to tell you about how to install the stainless steel corrosion-resistant metal pump. First, the stainless steel corrosion-resistant metal pump before installation: 1. Check the equipment drawings to understand the main dimensions of the pump, connectors and anchor bolt location. 2. Choose a reasonable installation location, to ensure smooth pump operation, to avoid resonance, in order to extend the life of the pump. 3. The necessary tools must be prepared prior to installation, equipped with suitable lifting equipment and adequate light when required, and large parts must be provided with suitable space and access to the mounting location for easy installation and adjustment of the pump. 4. Before installing the pipeline, in order to protect the pump, the pump flange and the larvae L on the Screw thread should not be torn off so as to avoid human debris. The pump must be covered during installation. 5. For the shaft seal, pump outlet, cooling system, etc. must provide a pressure drain conditions, so as not to pollute the environment. 6. After the pump foundation and related civil works are completed, the concrete reaches an effective curing period, the strength reaches the prescribed standard, and after review and acceptance, the pump can be installed in place. Second, the suction and exhaust pipe installation: 1. When installing the horizontal pipe, the liquid inlet pipe diameter should be gradually increased to the end, the liquid end of the pipe diameter should be gradually reduced to the end, so to avoid the airbag. 2. The use of support piping, mainly to prevent the pump inlet and outlet pipes due to pipe weight and thermal stress generated by force and torque beyond the maximum allowable pump nozzle mouth to avoid deformation of the pump. 3. Design is conducive to the flow of import and export management. When changing from small tube diameter to large tube diameter, it should be gradually transferred. The rule is: the length of the conical transition section is equal to 5 ~ 7 times of the standard diameter difference. 4. Irregular transition pipe sections and elbows with smaller radius of gyration should be avoided, otherwise pipe resistance will be increased. Especially for the suction pipe of the pump, the larger pipe resistance will cause the pressure at the pump inlet to decrease, which will affect the suction capacity of the pump. Seriously, the pump will cavitate and will not work normally. In the case of several pumps, a separate suction line must be provided for each pump in addition to the spare pump. The reserve pump and the corresponding pump share a single suction line because there is always only one pump in use. 5. For the flange connection, should ensure that the two flanges parallel to each other, and does not allow the gasket between the flange cover the pipeline access. Third, the corrosion-resistant metal pump base installation: 1. The base with the pump and motor on the foundation, the anchor bolts into the anchor bolt holes in the base, spiral washer and nuts, with different thickness and different forms Adjust the pump to a horizontal position with a steel backing plate. 2. Clear the anchor bolts reserved hole water and debris, perfusion with concrete anchor bolts. 3. After the concrete is solidified, tighten the anchor bolts and nuts. Re-check the level of the pump, such as pump position changes must be corrected again. 4. After the secondary grouting with concrete, the concrete should fill the entire space under the base, that is to be poured into contact with the roof, the sump and all the stiffeners. Welded base to perfusion to the base surface of the base of the channel.
